본 논문은 생성모델의 학습데이터 제작기법에 대한 실험 및 결과와 향후 관련 연구의 방향을 기술한다. GAN으로 대표되는 생성모델이 아티스트에게 얼마만큼의 만족도와 영감을 주는지를 비교 실험 및 평가하기 위해서는 정제된 학습데이터가 필요하다. 하지만 현실적으로 아티스트의 작품은 데이터 세트를 만들기에는 그 수가 적고 인공지능이 학습하기에도 정제되어있지 않다. 2차 가공작업을 통하여 아티스트의 원본 작업과 유사한 데이터 세트의 구축은 생성모델의 성능향상을 위해 매우 중요하다. 연구의 결과 생성모델이 표현하기 어려운 스타일의 작가 작품을 선정한 뒤 최적의 학습데이터를 만들기 위한 다양한 실험과 기법을 통해 구축한 데이터 세트를 생성모델 알고리즘에 적용하고 실험을 통해 창작자의 작품제작 의도인 작가 진술에 최대한 유사한 이미지의 생성과 더 나아가 작가가 생각하지 못했던 창조적 모방의 결과물을 도출하였고 작가평가를 통해 높은 만족도를 얻었다.

조현병(정신분열증)은 사고, 감정, 지각, 행동 등 인격의 여러 측면에 걸쳐 광범위한 임상적 이상 증상을 일으키는 정신 질환이다. 심각한 정신 질환임에도 불구하고 여전히 과학적 진단 체계가 갖춰져 있지 않아 진단의 많은 부분을 환자의 진술에 의존하고 있으며, 이로 인해 조현병이라는 진단을 받고 치료방법을 찾는데 까지 오랜 시간이 걸린다. 이에 본 연구는 EEG, MRI 데이터와 조현병의 상관관계를 이용한 조현병 진단 시스템을 제안하고자 한다. 본 시스템은 MRI 데이터와 머신러닝 알고리즘을 통한 조현병의 확률적 진단과 함께, EEG 데이터의 시각화 기능을 제공하는 소프트웨어를 개발함으로써 조현병 진단의 과학적 근거를 의사에게 제공하여 정확한 병의 진단을 목표로 한다. 진단 후에는 환자 데이터의 체계적 관리를 통해 머신러닝 알고리즘의 학습 데이터 확보 및 환자의 상태를 지속적으로 관리·관찰 할 수 있도록 하여 의료 소프트웨어로서 조현병의 체계적 진단 및 관리 시스템을 구축한다.

This research is designed to evaluate perception of "the role of broadcasting in the process of unification" among South Korean propaganda broadcasting experts. This research used Q-methodology for in-depth evaluation of the experts' perception towards propaganda broadcasts. Total sixteen experts who work at the propaganda broadcasting company domestically or internationally as well as conduct related researches were selected as P-samples. This research listed sixty Q statements covering issues such as Perception of Unification, General Propaganda Broadcasts, Private Propaganda Broadcasts, Communication between North and South Korea. According to traditional way of Q-analysis, it drew two types of perception; Type 1: North Korean Liberal Broadcasts, Type2: Inter-Korean Exchange and Cooperation Broadcasts. For in-depth analysis, positive and negative statements were analyzed based on its tendency. As a result, positive statements tend to follow 'the Role of Unification Broadcasts' and negative statements followed 'the regulation of Private Broadcasts' When further researches were conducted on positive statements based on its axis of tendencies, Type 1 and Type 2 were categorized as follows; the Role of Unification Broadcasts- North Korean Liberal Broadcasts and Inter-Korean Exchange and Cooperation Broadcasts. On the other hand, when negative statements were analyzed based on its tendencies, the result of Type 1 and Type 2 were as follows; the Improvement of Private Broadcasts- Redeeming the Private Propaganda Broadcasts and Criticizing Private Propaganda Broadcasts. Regardless such differences, experts do agree on the idea which emphasize the role of broadcasts in the process of unification and also they share the same thought on the need to improve the private propaganda broadcasts. This research expected to contribute to society by making differences in analyzing propaganda broadcasting experts' perception in an objective and positive way compare to other existing researches. Therefore, it proposes several suggestions to consider when producing propaganda broadcasts.

This study aimed at understanding the experience in deciding for childcare of unmarried lone mother and searching for intervention methods through in-depth examination of the essence of the experience. To achieve this, the Colazzi analysis of phenomenological research was applied. The subjects of study were 7 unmarried lone mothers in early age of the twenties and thirties, who resided in an institution for unmarried lone mothers. An in-depth interview was held individually with them with question of "What is the experience in deciding for childcare as a unmarried lone mother" twice on the average from Nov. 2003 to Feb. 2005. The results found that a unmarried lone mothers' experience in childcare meant 'resurrection' through analyzing 22 themes and 7 theme clusters(confusion due to pregnancy, harsh feeling for reality suffering alone, feeling of love for a baby, mental conflict about childcare, decision toward childcare, firm in decision, hope for resurrection). Although the results of this study have the limitation of generalization due to phenomenological study, it will contribute to accepting and understanding mother-and-child families as one type of family rather than regarding them as being difficult or alienated in family and society, to recognizing the need of taking back their rights, and to suggesting intervention methods for unmarried lone mothers.

The purpose of this study is to analyze the conceptual simulation observed when students are thinking about the causes of the seasonal change, identifying how students come up with the explanation. For this study, a framework for conceptual simulation process and strategy based on literary research was developed and its validity was proved by four experts in the field of science education. The results were as in the following: First, through the process of explaining the causes for seasonal change, students usually base their explanation on perceptual experience learned from model experiments from a science class. Besides, construct of thought experiment using the familiar object or analogize of the familiar perceptual experience. These all contributed to on explanation firmly. Second, errors from mental simulation were found in the statement of initial representation and running imagistic simulation. It happened when statement of initial representation is not in a complete and secure state or when participants think of an inappropriate situation during running imagistic simulation. Third, the study identified that the use of strategies like 'removal' and 'replace' was shown to enhance the effects of conceptual simulation particularly in regard with solar attitude at meridian passage.

The purpose of this study was to explore early childhood pre-service teachers' belief in homosexuality. This study applied the Q-method to investigate teachers'subjective awareness of homosexuality. Using an open questionnaire, we asked participants to describe how they think about homosexuality. Forty-five pre-service teachers were Q-sampled. Using the QUANL program, 45 statements were classified into 9 levels. Results revealed that image types of early childhood pre-service teachers can be classified into four distinguished categories: 1) type of respect: to regard gays and lesbians as normal people who love the same sex, 2) type of acknowledgment: to regard them as very unique people who attract people's attention, 3) type of relation-denying: to regard them as someone who were born totally differently, and 4) type of extremely denying-to regard them not being respected and disgusting. Most of the teachers seemed to have a tendency to acknowledge and respect individuals'sexual orientation. However, some pre-service teachers still have a negative attitude toward homosexuality. The significance of this study is to reveal the silenced issue, that is, sexual orientation in the field of early childhood multicultural education. Teachers can have a strong effect on young children's belief about sexual identity and sexual orientation. It would be important to look back on educators'perspective on homosexuality before suggesting the direction of multicultural education of young children related to the issue of sexual orientation.

The purpose of this study was to investigate the effects of prior-knowledge level and supportive information types in web-based learning using 4C/ID model(Four-Components Instructional Design model) on cognitive load and schema acquisition. To achieve the purpose, this study applied a web based learning. 166 university students participated in web-based learning for 4 weeks. After web-based learning, they checked self report for cognitive load and made concept map for schema acquisition and the datum from them were used for 2 ways ANOVA. According to the findings, groups in prior-knowledge level invested significantly differences on cognitive load and a question group in case of supportive information types didn't invested significant differences on cognitive load with statement group. Second, groups in prior-knowledge level invested significantly differences on schema acquisition and a question group in case of supportive information types invested significantly higher schema acquisition than a statement group. Furthermore, it happened interaction effect between supportive information types and prior-knowledge level on schema acquisition. This research has several implications with regard to suggesting the guidelines and conditions for the authentic task of the novice.

We examined how science teachers in academic high schools perceived the 6th science curriculum and how they practiced under the curriculum. A nationwide survey was administered to obtain the responses from 402 teachers of 135 high schools. Most thought that the main themes of curriculum revision were well-embedded in the 'objectives', and that the 'content and content structure' were proper. However, they thought that the 'objectives' were not stated explicitly enough to develop teaching materials and to improve actual teaching and evaluation, and that some statements in the sections of 'method' and 'evaluation' were not proper if considered actual teachers' ability to teach inquiry and educational facilities. Many teachers also felt that the information about the curriculum was not sufficiently included at in-service teacher training programs, and that students' knowledge, attitude, and problem solving ability were not enhanced. Only few teachers were found to apply the STS approaches, reconstruct lessons, vary the structure of learning group, and develop evaluation tools with their colleagues. The lack of the practices was explained by entrance-examination-centered instruction and assessment, poor educational facilities, and lack of innovative teaching materials.

This paper was written for the purpose of seeking a radical answer to the reason why we feel an actuality while watching a digital animated film. In the world of digital animation, there exist surrealistic subjects and the objects, which have come been brought into life, play their own role there. Furthermore, objects, which do not exist anywhere in the real world, appear and are closely connected with each other by means of a time discourse. Their world seems to be identical to our world or not. This study defined an actuality of a digital animation world as an actuality of Imaginary reality, an actuality of existent object, an actuality of anonymous object and an actuality time discourse, and examined such actuality. A frame of concept for examining the actuality was borrowed from philosophical statements of phenomenology that understands the nature of an actuality through 'zu den Sachen selbst'. Philosophical statements cited for searching an actuality specifically were those already explained by E. Husserl, M. Heidegger, J.-P. Sartre, G. Bachelard, M. Merleau-Ponty, and P. Ricoeur, Methodologically, this study attempted to understand our existence and recognition of the world in a phenomenological point of view, apply this principle to the world of a digital animation, and subsequently discuss it with the provision of examples. The purpose for this study is to reconsider the fundamental moaning of a digital animated film and evaluate its value.
